JALOUSIE WINDOW LOUVER Filed Aug. 18, 1950 INVENTOR. day/v M 5/ /70 WPatented Jan. 26, 1954 UNITED STATE T OFFICE 3 Claims.

This invention relates to improvements in jalousie windows, and moreparticularly to means for removably mounting individual louvers of suchwindows in the frames thereof, the primary object of the invention beingto provide such mounting means in the form of clips composed of twosections which are frictionally engaged in such a manner that thesections can be quickly and easily separated to enable removal of adamaged louver and can be quickly and easily reengaged to install areplacement louver, all without removing or working upon the windowframe or in any way damaging or defacing the frame or subjecting thelouvers, which are usually of glass, to marring or breakage.

Other important objects and advantageous features of the invention willbe apparent from the following description and the accompanyingdrawings, wherein merely for purposes of illustration herein, a specificembodiment is set forth in detail.

In the drawing, wherein like numerals designate like parts throughoutthe several views:

Figure 1 is a fragmentary transverse vertical section taken through ajalousie window frame showing louvers mounted therein in accordance withthe present invention, only one of the side members being shown;

Figure 2 is an enlarged inside elevation of one of the mounting clips;

Figure 3 is an outside elevation thereof;

Figure 4 is a top plan view of Figure 2;

Figure 5 is an outer end elevation, looking from right to left in Figure3;

Figure 6 is an inner end elevation, looking from left to right in Figure3; and

Figure 7 is a transverse vertical section taken on the line 7-1 ofFigure 2.

Referring in detail to the drawing, the numeral 9 generally designates ajalousie window frame having the vertical side members I0, only one ofwhich is shown, between which the glass or other similar materiallouvers II are horizontally disposed in vertically spaced relation indeclining planes. In accordance with the present invention the oppositeends of the louvers II are secured in clips, generally designated I2,which mount the louvers on the window frame side members I0.

The clips I2 are similar but are reversed in position on the oppositeends of the louvers II. Each clip I2 comprises a bracket section A,adapted to be secured in place on the frame side member ID by means ofrivets I3 or other suitable means, and a holder section B, in which theoutward longitudinal edges by a web 22.

adjacent end of the louver is supportably inserted and confined.

The bracket section A comprises a plane vertical plate I4, adapted toengage the inner side of the frame member I flatwise, formed withvertically spaced holes l and It to pass the securing rivets I3. Theplate It has a perpendicular rear edge I! and a forwardly decliningforward edge i8, and a forwardly declining and less angulated lowerright angular edge on which is a laterally inwardly projecting planeflange :9 having a free edge I9 parallel to the plate I 4. The flange I9has the declination corresponding to the desired declination of thelouver I I.

The holder section B comprises a channel form comprising upper and lowerparallely spaced sidewalls or flanges and 2| respectively, spaced tosnugly receive therebetween an end of the associated louver II, andconnected at their The lower flange 2I is plane and unindented and itselevated end 23 terminates in downwardly or laterally inwardly spacedrelation to the elevated end of the elevated flange 20. The upper end ofthe upper flange is has a downturned upper stop flange 24 while thedepressed end of the lower flange 2| has an upturned stop flange 25, thestop flanges 24 and 25 being spaced to snugly engage the upper and loweredges, respectively, of the louver I I when inserted between the flanges20 and 2|.

The depressed end of the upper flange 28 of the holder section B isspaced upwardly or laterally inwardly from the depressed end of thelower flange 2i and is bent upwardly and inwardly to provide a lowerhook 26. At a point intermediate its elevated and depressed ends theupper flange I0 is slit transversely to define a lower transverse edge2's in the plane of the flange 20 and the upper edge 28. A portionadjacent to the upper edge 28 is directed upwardly at right anles fromthe flange 20 to define a shoulder, and the shoulder 30 terminates atits upper end in a downwardly directed terminal 2! which is parallel tothe flange 20 and is upwardly spaced from the flange 20 at a distancesuch that the flange I9 of the bracket section A can be snugly andfrictionally received between the terminal 29 and the upper surface ofthe flange 20. The shoulder 30 is spaced upwardly from the lower hook 25at a distance corresponding to the length of the bracket section flangeI9 so that when the bracket flange i9 is engaged between the shoulder 30and the stop hook 26 there is a minimum of lost motion of the holdersection 3 in a direction lengthwise of the bracket section flange l9.The stop hook 26 is not initially in the form of a hook, but in the formof a straight piece extending upwardly from the depressed end of theflange 20, the terminal part of the piece being adapted to be bentdownwardly or laterally inwardly to form the stop hook 26.

Two of the bracket sections A having been mounted in longitudinalalignment on the Window frame side members, In, and holder sections Bhaving been slipped onto the opposite ends of a louver II, the louver isinstalled by passing the holder sections B upwardly under the flanges [9of the bracket sections A and engagingtheter;

Then, with the shoulders l engaging the saidelevated edges of the flanges 2B, the lower portions of the flanges 2are brought up-agai'n'st the undersides of thesefportions of the flangeser nl l rmin so e nd por ions of the pieces are bent laterallyinwardlyoyer and; downwardlympon; the depressed; ends of; the bracket flanges.19 and pigeferably sgueezedtight to securely grip the flanges] 9:,andformthe lower hooks. v v g In the event that it be desired to removethelouver H, it is necessary, only to bend up, the terminal or freeendportion of the hook 25., This frees the holder sections 13 to beremoved from theflanges I9 0 f the bracket sections A by a removal ofthe 1ou ve 3s described above. It is to be observed thatin; installingand removing a, louver no manipulation of, o mutilation of the bracketsections A is; involved, and that, in the event that the; hook, 25 05,any holder section should break; oifinbeingbent in installing orremoving av louver, the-pffending holder section B can be readilyremoved and replacedrelativeto e ve t ut in: an lw vi volvin the bracketsections A on; the. window frame side members [0,
